Adds OFFICIAL_APP_REVERSE_ENGINEERING.md — a technical teardown (methodology,
auth model, device-ID, GPS, Instabug) with mermaid diagrams and the mitmproxy
capture timeline.
Corrects OFFICIAL_APP_PRIVACY.md, which was wrong on two counts:
- IMEI: the app reads no IMEI; it sends the Android SSAID to /api/Device in a
field misleadingly named IMEINumber.
- Trackers: Segment/Amplitude/Firebase-Analytics/Sentry/ad-ID are all ABSENT;
the real telemetry SDK is Instabug (session replay, screenshots, network logs).
Also folds in the confirmed GPS auto-send (with the GrapheneOS caveat).
